CUBE BOX.

SPECIFICATION forming part Of Letters Patent NO. 508,298, dated November7, 1893. Application filed June 22, B93. Serial No. 478.527. (No model.)

To all whom it may concern.-

Be it known that I, NEWTON Z. FULTON, of Gunniso'n, in the county ofGunnison and State of Colorado, have invented a new and usefulImprovement in Cube Boxes, of which the following is a specification.

My invention is in the nature of an educational appliance for thepurpose of demonstrating plane and solid geometry, and to this end itconsists in a cubical shaped box designed to receive and act as areceptacle for the various models of plane and solid geometric formssuch as cylinders, conesf'cubes pyramids, globes, squares, triangles,ellipses, parallelograms, 850., and having also on the outer walls ofthree sides of said boxhinged sections which when folded form a perfectcube of larger size than the box, and which sides have also other hingedsections which by their movable character serve to illustrate theprinciples of square and cube root by the segregable character of one ofthe aliquot parts of said square or cube, all as hereinafter fullydescribed.

Figure 1 is a view in perspective of the box the device with its hingedsection opened and 'with a portion of the box broken away to show thestorage within the same of various other geometric forms.

In the drawings A represents the box or receptable which is a perfectcube with equal sides. Within this box or receptacle are contained thevarious other geometric forms used for illustrating plane and solidgeometry such as the cylinder, globe, cube, pyramid, cone, square,triangle, ellipse, parallelogram, &c. The top F of this box is made tofit down within the sides of the box so as to be flush with their upperedges, and is provided with hinges a at one side, and a flush or nonproj ecting handle or pull b. To each of the three sides of the box atone of their edges is hinged a folding section, which are all of thesame size, and correspond in square dimension to the sides of the box.The top folding section B is hinged at one side to the upper horizontaledge of the box, and has also hinged to it in turn at its free edge asmaller supplemental section B whose length is the same as one of theside sections 13, and whose cross section is a perfect square.

0 isone of the side folding sections. The square dimensions thereof areequal to one of the sides of the box, and it is hinged at c to one ofthe vertical edges of the same, and in turn has hinged to its upper edgeanother supplemental section 0 equal in length to the side of the box,anda square in cross section.

D is the third of the side folding sections. Like the others its squaredimensions are equal to those of the side of the box, and itis hinged atd to one of the vertical edges of the box, and has attached to its freeedge a supplemental section D whose length is equal to the side of thesection and whose cross section is a square. To the end of thissupplemental section D is hinged a further supplemental section D whichis a perfect cube with all square sides equal to the cross section ofall the supplemental sections B O D. When all of these hinged sectionsare folded about the box they make a perfect cube, and when unfolded, asin Fig. 2, they illustrate the analysis of the cube into its aliquotparts of which D is one, and this serves to illustrate square and 7 cuberoot in the following way: Supposing the top of the closed box to bedivided into aliquot parts, of which D is one, and there are six ofthese aliquot parts in each row, and six rowsof them, it will be plainthat there will be thirty six aliquot parts similar in size to D and thesquare root of thirty-six will be six or the'number of times that suchnumber must be multiplied by itself to equal thirty six. aliquot spaceso that six corresponding areas will lie under each aliquot section D wewill have thirty six multiplied six times to make two hundred andsixteen, the cube root of which is six or the number which multiplied byitself and the product then multiplied again by itself equals twohundred and six teen. In this way, owing to the segregable character ofthe parts, ocular demonstration of square and cube root is clearly andforcibly given, and yet the parts are all connected together and are notcapable of being detached and lost.

As the device is made of sufiicient size to act as a receptacle forother detached geometric forms within, the hinged sections all aresecured by catches e, and an external handle E is provided so that thedevice maybe conven- Now measuring down from each iently transportedwithout opening and spilling its contents.

I am aware that a small and solid cube has been provided withsupplemental folding sections corresponding in the main to .my sectionsB C D D and I do not claim this broadly. My invention is distinguishedby the fact that it is constructed as a box or receptacle ofconsiderable size with flush lid and handle for the storage of geometricforms, and by the fact that the hinged sections are provided withlocking devices and a main supporting handle.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The cube box herein described consisting of a hollow receptacle madein the form of a cube with an adjustable flush door or lid; combinedwith three hinged folding external sections of the same squaredimensions as the box having supplemental hinged sections equal inlength to sides of the box and of square cross section, one of saidsupplemental folding sectionsbein g provided with a hinged block forminga perfect cube whose square is equal to the square cross section of thesupplemental hinged sections, substantially as and for the purposedescribed.

2. The cube box herein described consisting of a hollow receptacle madein the form of a cube with an adjustable flush door or lid;

combined with three hinged folding external sections of the same squaredimensions as the box two of said hinged sections having a supplementalfolding section on their free edges parallel to the hinges, and thethird section having a folding supplemental section on its edge at rightangles to its hinged edge, and one of said hinged supplemental sectionshaving a hinged cube whose square equals the cross section of thesupplemental sections substantially as and for the purpose described.

3. The cube box herein described consisting of a hollow receptacle madein the form of a cube with an adjustable flush door or lid; combinedwith three hinged and folding sections of the same square dimensions asthe box, and having supplemental hinged sections equal in length to thesides of the box and of square cross section, one of said supplementalfolding sections being provided with a hinged block or cube whose squareis equal to that of the cross sections of the supplemental hingedsections, catches or fastenings for holding these hinged sections inlocked position, and a handle for lifting and transporting the entiredevice substantially as and for the purpose described.
